Since you are using Rails and this seems to be related to a view, there's number_with_precision:

number_with_precision(500, precision: 2)
#=> "500.00"

I18n.locale = :de
number_with_precision(500, precision: 2)
#=> "500,00"

For currencies I'd suggest number_to_currency:

number_to_currency(500)
#=> "$500.00"
